MarketsandMarkets projects that the aluminum casting market size will grow from USD 55.56 Billion in 2017 to USD 79.13 Billion by 2022, at an estimated CAGR of 7.33%. The aluminum casting market is witnessing considerable growth due to advancements in technology and high efficiency of aluminum casting. The aluminum casting market has immense opportunities as aluminum is preferred over iron and steel products in the automobile industry; moreover, investments in the automobile industry is growing, which will drive the demand for cast aluminum products.
On the basis of process, the aluminum casting market is segmented into die casting, permanent mold casting, and sand casting. The die casting process is projected to grow at the highest CAGR during the forecast period. The dominant market position of the die casting segment can be attributed to the excellent efficiency and the economical nature of the process that offers a broader range of shapes and components than other casting techniques. Die casting is extensively used in the automobile sector for parts such as engine blocks, wheel spacers, and valve covers.

In terms of value, the transportation segment, by end-use, is projected to grow at the highest rate during the forecast period. This growth is attributed to the growing demand for lighter automobiles globally, which has led to the replacement of steel and iron parts in automobiles with aluminum products. The rising demand for aluminum cast products in the transportation sector is attributed to the growing popularity of lightweight vehicles with better fuel efficiency.

In 2016, the Asia-Pacific market accounted for the largest share of the global aluminum casting market, followed by Europe and North America. However, as the aluminum casting market in developed countries is maturing, markets in developing countries such as China, India, and Turkey are projected to grow at a higher rate from 2017 to 2022. Asia-Pacific is projected to grow faster than any other region-level market, owing to the rapid expansion of applications such as automobiles, heavy machinery, building & construction, and mass transportation. China and India, among others, are investing in the infrastructure and manufacturing industries, which is expected to drive the transportation sector in the region, and in turn, drive the aluminum casting market as well

Currently, Asia-Pacific is the largest market for aluminum casting where India and China are the major country-level markets. The Asia-Pacific aluminum casting market is projected to register the highest CAGR during the forecast period, as it is the most widely populated region in the world, and subsequently, witnesses a high growth trend in the transportation and building & construction sectors. Characteristics such as lightweight and strength of cast aluminum are the major factors driving the rising demand for aluminum casting in the region. The durability and ability to bear high temperature are also influencing the application of cast aluminum products in the transportation and other sectors in Asia-Pacific region. However, replacement of aluminum alloy with magnesium, where strength and lightweight characteristics are the main requirements, and high-temperature tolerance properties are given secondary importance, as well as an economic downturn in developed regions are factors restraining the growth of the aluminum casting market.
